Terms | Definitions |
|---|---|
 an infectious agent | pathogen |
| if a microorganism is present or invades a host, grows and or multiplies but does not cause infection it is known as | colonization |
| T/F, an infectious disease may not pose a risk for transmission | true |
| if infectious disease can be transmitted directly from one person to another | communicable diseases |
| if pathogens multiply and cause clinical signs and symptoms | symptomatic |
| if clinical signs and symptoms are not present | asymptomatic |
| sufficient number of organisms | dose |
| ability to survive in the host or outside the body | virulence |
| susceptibility of the host | host resistance |
| has impaired immune system | immunocompromised |
| a place where a pathogen can survive but may or may not multiply | resevoir |
| what things are required for a proper environment for organisms to thrive | food, oxygen, water, temp, pH, and light |
| require oxygen for survival and for multiplication sufficient to cause disease | aerobic |
| thrive where little or no free oxygen is available | anaerobic |
| this type of organism causes more infections in humans | aerobic |
| prevent growth and reproduction of bacteria | bacteriostasis |
| destroys bacteria | bactericidal |
| place where organism can exit and enter another host and cause disease | portal of exit |
| way organism is transmitted | modes of transmission |
| transmitting the virus when it bites the host | vector |
| organisms enter the body the through same routes they use fro exiting | portal of entry |
| this depends on the individual degree of resistance to a pathogen, immune response | susceptibility |
| ability of the pathogen to produce an infectious disease in an organism | pathogenicity |
| client usually experiences localized symptoms, such as pain and tenderness at the wound site | localized |
| an infection that affects the entire body instead of just a single organ or part | systematic |
| protective reaction that serves to neutralized pathogens and repair body cells | inflammatory response |
| these do not usually cause disease when residing in their usual area of the body but instead participate in maintaining health | normal flora |
| this develops when broad spectrum antibiotics eliminate a wide range of normal flora organisms not just those causing infection, bodys defenses are reduced which allow disease producing microorganisms to multiply causing illness | suprainfection |
| body's cellular response to injury, infection, or irritation is termed what | inflammation |
| dead tissue | necrotic |
| fluid and cells are discharged from cells or blood vessels | exudates |
| accumulation of fluid appears as localized swelling | edema |
| process that involves the destruction and absorption of bacteria | phagocytosis |
| an increase in the number of circulating WBC's, body's response to WBCs leaving blood vessels | leukocytosis |
| clear, like plasma, exudate may be this | serous |
| exudate containing RBC | sangineous |
| exudates may contain WBC and bacteria | purulent |
| formerly known as nosocomial, this results from delivery of health services in a health care facility | health care associated infections |
| type of HAI from a diagnostic or therapeutic procedure | iatrogenic infection |
| it is present outside the client, such as postoperative infection | exogenous infection |
| these are part of the persons normal flora or virulent organisms residing that could cause infection, can occur when normal flora becomes altered and an overgrowth results ex C DIF | endogenous infection |
| clean technique, includes procedures used to reduce the number of organisms present and prevent the transfer of organisms | medical asepsis |
| certain principles and procedures to prevent and control infection and its spread | standard precautions |
| this includes using an instant alcohol hand antiseptic before and after providing client care, hand washing with soap and water when hands are visibly soiled and performing surgical scrub | hand hygiene |
| the act of washing hands with soap and water followed by rinsing under a stream of water for 15 seconds | hand washing |
| complete elimination or destruction of all microorganisms includings spores | sterilization |
| process that eliminates many or all microorganisms with the exception of bacterial spores from inanimate objects | disinfection |
| cover mouth or nose when coughing or sneezing | cough etiquette |
| gowns, respiratory protection, eye protection, gloves are examples of what | PPE |
| cause and effect of the disease | epidemiology |
| sterile technique prevents contamination of an open wound, serves to isolate the operative area from the unsterile environment, and maintains a sterile field for surgery | surgical asepsis |
